Definitions

  • the present invention relates to a substrate which is formed into a three dimensional article.
  • Fiber reinforced composite structures enjoy the benefit of being lightweight while providing mechanical advantages such as strength. However, in many applications, molded plastic, wood or metal structures are preferred due to the cost involved, since they are relatively easy to fabricate. Often times however, articles, such as package or storing crates, are prone to damage due to the rough handling involved or are limited in their stacking ability due to weight and strength considerations. While fiber reinforced composite structures would be more desirable, the expense involved in making a somewhat complex three dimensional (3D) structure is a consideration.
  • composite structures start off typically with a woven flat substrate of fibers.
  • the substrate then has to be shaped into the form of the article which is then coated with a resin and thermoformed or cured in the desired shape.
  • This may be readily done for relatively flat or smooth surfaces.
  • cutting or darting is required. This is somewhat labor intensive and adds to the cost of manufacture. For things typically considered to be iriexpensive, for example a packaging crate, the added expense may outweigh the benefits of it being reinforced.
  • 3-D structures made out of fiber reinforcement it is also desirable to make 3-D structures out of 2-D sheet material which may be sheet metal, plastic, cloth, paper, cardboard, etc.
  • DE-A-19 716 637 describes a sheet of foldable honeycomb and method of folding this sheet according to the preamble of claims 1 and 8.
  • the present invention is directed toward providing a specially designed sheet of material for a 3D structure. It starts off as a 2D structure that is then formed into a 3D structure, particularly one having deep draws. To provide for this, the sheet of material is formed in a manner that has areas which would gather and distort the edges of the 3D structure which is formed by folding the sheet. The edges of the remaining portions of the sheet which formed the boundary of the removed area can be left as is or can be seamed using methods such as welding, thermal bonding or adhesive bonding.
  • FIG. 1 there is shown a flat 2D sheet of material 10 which illustrates the present invention.
  • the sheet 10 may be made of sheet metal, plastic, cloth, paper, cardboard or any other material suitable for the purpose.
  • the sheet 10 has been divided into regions or areas 12 through 28 divided along fold lines 30-36.
  • the sheet material has either been removed or the sheet formed without it leaving an open space.
  • the sheet 10 is constructed, it can then be formed into the desired shape.
  • FIG. 2A shown in Figure 2A is the flat 2D sheet 10.
  • the sheet 10 is then folded along fold lines 30 and 32.
  • the sheet 10 is then folded along fold lines 34 and 36 which are perpendicular to the fold lines 30 and 32 as shown in Figure 2C.
  • the edge or corner 38 so formed can be left as is or can be seamed by way of, for example, welding, thermal bonding, adhesive bonding or other means suitable for the purpose. Folding can be done automatically or by other means suitable for this purpose.
  • the foregoing advantageously avoids the need for cutting or darting, thereby reducing the amount of labor required and the ultimate cost of the article.
  • the present invention allows for the increased automation of the fabrication and therefore broadens the applications for which such structures may be used.
  • Sheet 110 illustrates a plurality of regions 120 wherein the sheet material has been removed. With such a sheet 110, it may be folded and shaped into a complex structure 130 as shown in Figure 4. Of course other shapes can be created by varying the size and location of the regions where the material is removed.

Claims (14)

  1. Feuille de matériau plane pour former une structure tridimensionnelle, ladite feuille comprenant :
    de la matière formant une première partie de la feuille (12, 14, 16, 18, 22, 24, 26, 28);
    une deuxième partie (20; 120) de la feuille sans matière, ladite deuxième partie comprenant deux premières arêtes parallèles entre elles, et deux deuxièmes arêtes parallèles entre elles et perpendiculaires aux premières arêtes, lesdites premières arêtes et lesdites deuxièmes arêtes définissant la deuxième partie de la feuille ; et
    dans laquelle la feuille comprend deux premières lignes de pliage (30, 32) s'étendant le long desdites premières arêtes et des deux côtés de celles-ci et allant jusqu'à l'arête de la première partie de la feuille, et deux deuxièmes lignes de pliage (34, 36) s'étendant le long desdites deuxièmes arêtes et des deux côtés de celles-ci et allant jusqu'à l'arête de la première partie de la feuille,
    caractérisée en ce que lesdites deux premières arêtes et lesdites deux deuxièmes arêtes de ladite deuxième partie de la feuille sont continues.
  2. Feuille selon la revendication 1, dans laquelle la deuxième partie de la feuille est entourée de la première partie.
  3. Feuille selon la revendication 1 ou 2 qui comprend une pluralité de premières parties et de deuxièmes parties.
  4. Feuille selon la revendication 3, dans laquelle les deuxièmes parties sont entourées de premières parties.
  5. Feuille selon l'une des revendications 1 à 4, dans laquelle une desdites lignes de pliage correspond à une desdites arêtes de la deuxième partie.
  6. Article tridimensionnel, caractérisé en ce qu'il comprend une feuille pliée selon l'une des revendications 1 à 5 et une arête fixée ou un coin fixé (38), formés lorsqu'une première partie de ladite feuille plane se trouve en condition d'aboutement.
  7. Article tridimensionnel selon la revendication 6, caractérisé en ce que ladite arête fixée ou ledit coin fixé (38) est une arête ou un coin (38) soudé ou thermoscellé ou collé.
  8. Procédé pour former une structure ayant une forme tridimensionnelle en utilisant une feuille, le procédé comprenant les étapes suivantes :
    la préparation de la feuille pour former une première partie (12, 14, 16, 18, 22, 24, 26, 28) de la feuille contenant de la matière ;
    l'enlèvement d'une portion de la feuille pour former une deuxième partie (20 ; 120) de la feuille sans matière et qui comprend deux premières arêtes parallèles entre elles, et deux deuxièmes arêtes parallèles entre elles et perpendiculaires aux premières arêtes, lesdites premières arêtes et lesdites deuxièmes arêtes définissant la deuxième partie de la feuille ; et
    le pliage de ladite feuille le long de deux jeux de premières lignes de pliage (30 ; 32) s'étendant le long desdites premières arêtes et des deux côtés de celles-ci et allant jusqu'à l'arête de la première partie de la feuille, et deux deuxièmes lignes de pliage (34, 36) s'étendant le long desdites deuxièmes arêtes et des deux côtés de celles-ci et allant jusqu'à l'arête de la première partie de la feuille, pour créer deux jeux de secondes lignes de pliage qui sont perpendiculaires aux premières lignes de pliage,
    caractérisé en ce que lesdites deux premières arêtes et lesdites deux deuxièmes arêtes de ladite deuxième partie de la feuille sont continues et provoquent une disparition de la deuxième partie ce qui amène la première partie de la feuille à former une configuration d'aboutement le long des premières et deuxièmes lignes de pliage.
